Abstract

Sir,

We have read the nice article News and Views by Ms. Renugasundari (IJCEP Vol 6, Issue (3), Jul-Sep, 2019 page 104) about sleep deprivation and obesity. Smith and colleagues have observed that there is an association between sleep and gut microbiome diversity.[1] The microbiome composition observed by them shows that within phyla richness of Bacteroidetes and Firmicutes were positively correlated with sleep efficiency and abstract thinking. Several taxa (Lachnospiraceae, Corynebacterium & Blautia) were negatively correlated with sleep measures.[1] Haro and colleagues suggested that gut microbiota may be different in men and women and that these differences may be influenced by the grade of obesity.[2] Cao and colleagues have studied more than 62 thousand children aged 6 to 17 years in China and they observed that short sleep duration was associated with increased risks of more sugar beverage intake and less vegetable and fruit intake.[3] Bhutani and colleagues have found that sleep deprived participants changed their food choices and they ate food with higher energy density (more calories per gram like doughnuts, chocolate chip cookies & potato chips).[4]
